Approach This is an optically transmitted video from the Nereus vehicle to a communications node lowered in the water column from a surface vessel. There are a few points to make here, 1) the link is free space optical (FSO) at a data rate of 10Mbps, 2) the vehicle is free swimming, and wirelessly controlled using the FSO link and an acoustic modem, and 3) this is a first, that we know of, demonstration of an untethered, remotely controlled, underwater vehicle.» View Video (Media Player)

SharkThis video is also optically transmitted FSO, via the link described above. This six gilled shark was quite a surprise appearing from nowhere during an otherwise uneventful technical demonstration. It is an example of the diverse and unexpected life encountered in the deep ocean.» View Video (Media Player)
